AUTOMATIC FIRE-LIGHTER.

Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed December 10, 1907. Serial No. 405,971.

To all whom it may concern:

Be it known that I, STEPHEN EVERETT GAMBLE, residing at Sebastopol, inthe county of Sonoma and State of California, have invented a new andImproved Automatic Fire-Lighter, of which the following is aspecification.

My invention is in the nature of an improved construction of firelighting means, especially arranged, when energized or set in operation,for automatically feeding the fuel into a stove on the inflammablematter contained therein and simultaneously igniting the said fuel so asto set fire to the said inflammable matter.

My invention comprehends an attachment adapted for being readilyconnected to a fire box of a stove or range and comprising generally afuel holder, a charging chamber that communicates with the said holderhaving an offtake that leads the fuel therefrom into the fire box, avalve for normally closing the said oftake, a valve opening device andan electric battery, and a sparking coil device arranged, when energizedfor opening the valve and creating a jump spark at the discharge end ofthe oftake for igniting the fuel charge for firing the inflammablematerial in the fire box.

My invention, in its'more subordinate features, consists in thecombination of cert: in details of construction and peculiar arrangementof parts, all of which will be hereinafter fully described, pointed outin the appended claims and illustrated in the accompanying drawing, inwhich Figure 1, is a view that illustrates the general cooperativearrangement of the parts that constitute my invention. Fi 2, is avertical, longitudinal section of the uel holding and chargingmechanism, the charging chamber valve being shown closed and the magnetcontrolled valve tripping device in the normal or dead position. Fig. 3,is a similar view, parts being in their active or fuel feeding andfiring condition.

In the practical application of my invention, an apertured plug E ofinsulating material is fixedly inserted in the side of the fire boxportion of the stove or range indicated by S in the drawing, throughwhich passes a tubular extension (1 of a plug D hereinafter termed thejump spark plug.

10 designates a base board or plate which in practice, is suitablymounted at a safe distance from the stove or range and upon which isheld a charging chamber or reservoir G, with which connects a feed pipeat from the tank A that holds the gasolene or other volatile fluid.

To the bottom of the chamber or'reservoir G is secured an offtake pipe 9that is connected by an insulating joint K with the feed pipe 9 thatextends through the tubular. extension (1 of the jum spark plug D anddischarges into the fire box N on the inflammable material therein.

V designates a flap valve in the bottom of the chamber or reservoir Gthat is normally held closed by the fluid pressure thereon and whichserves to out 01f the fuel from the stove.

B designates dry batteries for generating electric energy for a magnet Mmounted on the base member 10, the armature F of which forms a lever forengaging a tri finger f 2 that slidably moves through the ottom of thereservoir G and engages the free end ofthe valve V, the parts being soarranged that when the circuit through the batteries is closed, thearmature E (which is guided in a slotted bracket f raises the finger f 2and lifts the valve V suniciently to allow for the outflow of the fluidto the stove fire box, it being understood that the valve V will be heldopen so long as the magnet M remains energized. For admitting fluid tobe held in the chamber or reservoir G, a valve a is located in the pipea as shown.

C designates a jump spark coil of any approved construction which is incircuit with the batteries B and with the sparking plug D, it beingunderstood that when the circuit of the batteries is closed by theswitch X suitably located, for example, in a bed room as shown in Fig.1, the magnet M and the jump spark coil are simultaneously energize Fromthe foregoing description taken in connection with the accompanyingdrawing, it is believed theadvantages and the manner in which myinvention operates will be readily apparent.

By pressing the switch button X the batteries B are connected, whichsimultaneously energizes the magnet M, shifts the armature F and opensthe valve V so as to allow a charge of the volatile fluid passingthrough the jump lug D into the fire box N where it is instant y ignitedby the electric spark or sparks caused by the energizing of' t e jumpcoil 0 which operation instantly ikgnites' the inflammable matter in thefire OX.

By providing a charging compartment fed from the tank A and operatingthe valve thereon as stated, the operation of feeding the fluid into thefire box is made positive and danger of leakage through the valvechamber is thereby reduced to the minimum since the lighting mechanismmay be set by charging the chamber G from the reservoir With therequired fluid necessary for lighting the fire and then cutting off thetank A from the said chamber or reservoir G by proper manipulation ofthe valve a Having thus described my invention, What I claim and desiretosecure by Letters Patent. is i 1. A fire lighting means comprising areservoir for holding a charge of fluid, an ofltake therefrom, a feedpipe connected with said off-take and adapted to be projected into afire box of a stove, a valve for the offtake pipe normally closed byfluid pressure in the reservoir, magnetically controlled means foropening the valve, a spark plug surrounding the projecting end of thefeed pipe, a spark coil in circuit with the delivery end of the feedpipe and with the spark plug and a switch controlled means forenergizing the magnet and coil.

2. The combination with a spark plug adapted to be inserted through theside of a stove or range, a charging reservoir for holding fluid, anofftake therefrom, a feed pipe that extends through the'spark plug, aninsulator joint that connects the said offtake and the feed pipe, anautomatically closed valve for controlling the outflow into the OE-take, electro magnet devices for openingsaid valve or coil in circuitwith the spark plug, and switch controlled source of electric energy incircuit with the electro magnet and the spark coil, as set forth.

3. In combination with a gasolene tank having a valved discharge pipe, acharging reservoir that connects with the discharge pipe, an off-takefrom said charging reservoir, a jump spark plug adapted to be projectedinto a fire-box of a stove, a feed pipe connected with said off-takepipe from the charging reservoir and projected through the spark plug,an insulator joint connecting the feed pipe With the off-take pipe fromthe charging reservoir, a valve for closing said off-take pipe from thecharging reservoir, said last named valve being normally closed by fluidpressure, a magnetically operated tripping device for opening said lastnamed valve, a spark coil in circuit with the spark plug and the feedpipe, a source of electric energy in circuit'with the spark coil and themagnetically operated tripping devices, a switch for controlling theaction of said source of electric energy, all being arrangedsubstantially as shown and described.
